This unit isn't constructed as an expedition bag with floating, overlapping v-channels. The long seams are sewnthrough but the comforter is so heavy & the fill so insulating that there are no cold spots. You can open your bedroom windows in January and still be toasty.

You probably would need to get a longer plastic tube than the one that is provided to do this.

I'm sure you could, but the cut edges would be ratty. They would be easy enough to sew or serge, if you're handy that way.

My kit came with two types of tube connectors round and triangle, hope that helps

There is a straw size tube that runs parallel to the large tube. It attaches to the top of that.

This uses dies, they probably have a square die. I would not buy this style, it's really outdated. You need one of the big shot or big kick. There's no end to the shapes they cut.

Not sure what they call them. If you have moderate sewing skills you can make them with a bit of elastic band from Wally World. A really good product is ITW Web Dominators that work very well. Come in colors to match webbing and plenty of YouTube videos on their implementation.

I made a circle pattern from shipping paper to fit my basket. I then cut two slits. One on each side where they would overlap. I then rounded off some of the top that protruded. Very pleased with the results.

There are cut outs on the top and bottom which could be the openings that person is asking about.

I have found that a heavy duty tubing cutter does the trick. Cut on the indents and it leaves a nice edge to put the plugs in the top. Make sure you cut off from the top :)

Square tubular. Solid steel would not be as strong. The bends give it strength.

I would look for a square one. You might find one by going to the products website.

They are spiraled and very long. There are videos on you tube that demonstrate this product.

One way is to slip the 1/4 in tube into the larger tube that fits the larger fitting.

this is not water tight as each piece has a seam all the way around it (12" X 12" squares)

If you mean square, no; these are shaped kind of like 'fat bullets' with a hole in the middle.
